Outcome Measures
Primary Outcomes (1)
Difference in scores of the State-Trait Anxiety Inventory-State (STAI-S)
Difference in scores of the State-Trait Anxiety Inventory-State (STAI-S) from the preoperative baseline (1 day before surgery) to the 5th day after surgery.
Postoperative 5 day
Study Arms (2)
Dexmedetomidine nasal spray combined with routine perioperative management
ACTIVE COMPARATORPatients in this group will receive dexmedetomidine nasal spray in the ward on the night before surgery and on the morning of surgery.The standard dose is 100μg. For subjects older than 60 years or weighing less than 45 kg, the dose is adjusted to 75 μg. Patients also receive the same routine perioperative management as the control group.
Routine perioperative management
NO INTERVENTIONPatients in this group do not receive any nasal spray intervention. Patients receive routine perioperative management.
Interventions
Patients will receive dexmedetomidine nasal spray in the ward on the night before surgery (before bedtime) and on the morning of surgery (about 1 - 2 hours before anesthesia induction). When administering the drug, the patient should sit upright with the head slightly forward, shake well before use and pre-pray to activate the device. The standard dose is 100μg (2 sprays in each nostril, 4 sprays in total, 25 μg per spray). For subjects older than 60 years or weighing less than 45 kg, the dose is adjusted to 75 μg (a total of 3 sprays, alternately sprayed into both nostrils, for example, 2 sprays in the left nostril and 1 spray in the right nostril, or vice versa).
